Every fuel injector type has a unique minimum injection time and latency for it to fully open since energized.
This latency is often referenced as injector lag- or deadtime, latency or delay (ip_ti_add_dly__vb).
It is strongly dependant on the supply voltage and therefore stored in an interpolated table.
The minimum injection time is also important to make sure the injection pattern is clear and complete. (c_ti_min_iv).
